From a tuning perspective, go with the 135i. Our z's top out at~325whp with full boltons and tune. That blows.
My mechanic's gf has a 135i with a tune and meth kit installed and making a little over 400whp.
If I want to beat her in a straight line then I'd have to go boost and that isn't cheap. I didn't get the z for straight line fun but More power doesn't hurt. After a few months, I started feeling like I needed more power
